Scalable Manufacturing of High-Nanotube-Content Nanocomposite Fabrics

Martinez-Rubi Y., Jakubinek M.B., Ashrafi B., Simard B., Kingston C.T., Palumbo G., McCrea J., Pallotta R., Katugaha H., National Research Council Canada, CA
Carbon nanotubes (CNTs) have long been considered promising for development of advanced composite materials, due to their unsurpassed properties along with low density, and they are now appearing in an increasing number of industrial applications [...]

Ferromagnetism and Giant Paramagnetism in Cu@C nanocomposites

Estiphanos M., Sharoyan E., Gyulasaryan H., Manukyan A., Mirzakhanyan A., Bernal O., Kocharian A., California State University Los Angeles, US
Different size copper nanoparticles coated by carbon are synthesized by solid phase pyrolysis of polycrystalline phthalocyanine (CuPc, Pc= C32N8H16). The structural properties of obtained powder products are characterized by XRD and Raman spectroscopy. The morphologies [...]

Graphene based core–shell additives for increasing the thermal conductivity of epoxy nanocomposites

Eksik O., Bartolucci S.F., Gupta T., Fard H., Tasciuca T.B., Koratkar N., Istanbul Technical University, TR
We studied novel technique to enhance the thermal conductivity of epoxy nanocomposites using graphene coated poly-methyl-methacrylate (PMMA) balls. PMMA balls with a diameter in the range of 200–300 nm were synthesized using suspension polymerization. These [...]

Quantum Modeling of Doped Carbon Nanotubes for High Ampacity Conductor Design

Li Y., Fahrenthold E., University of Texas at Austin, US
The development of new high strength, high reliability, high ampacity conductors can benefit a wide range of commercial and military systems. Improved conductors are needed to perform a variety of power and data transmission functions, [...]

Effect of CNT Morphology and Alignment on the Interfacial and the Elastic Properties of Nanocomposites

Alian A.R., Meguid S.A., University of Toronto, CA
Carbon nanotubes (CNTs) are typically curved, agglomerated and aggregated as a result of van der Waal interactions and electrostatic forces. It has been proven experimentally that CNT morphology and alignment affect the mechanical, electrical, and [...]

A novel demonstration of the dichroic effect exhibited by gold nanoparticles and their incorporation into polymer materials

Wrigglesworth E.G., Johnston J.H., Victoria University of Wellington, NZ
Gold nanoparticles have long been utilised for their attractive colours. A well-known example is the Lycurgus cup, dated at the 4th century, which appears red when viewed in transmitted light and green in reflected light [...]

Continuous Preparation of Polymer Nanocomposites for Applications in Novel Substrates, Multilayered Materials, and 3D Printing

Barry C., Kazmer D., Mead J., University of Massachusetts-Lowell, US
Polymer nanocomposites are composed of a nanofiller, such as nanoclay, carbon nanotubes, graphene, and nanosilver, in a polymer matrix. Depending on the choice of filler, these nanocomposites exhibit unique material properties, including improved barrier properties, [...]

Confinement Chemistry in Self-Assembling Polymer-Metal Nanoreactors

McTaggart M., Malardier-Jugroot C., Royal Military College of Canada, CA
We have developed and thoroughly characterized stable polymer-metal nanocomposite reactor systems with hydrophobic inner surfaces 2-3 nm apart. Previous work has shown that energetically unfavourable reactions, namely pyrrole polymerization and metal salt reduction, spontaneously occur [...]

Scalable Polymer Patterning (SP2)

Mead J., Barry C., University of Massachusetts-Lowell, US
Polymeric materials are easily fabricated into a wide array of structures for numerous applications. The bulk properties can be tailored for preparing novel structures and substrates for use as substrates for 3D printing. Particularly, the [...]

Multifunctional Nanocomposites for Oil and Gas

Sherman A., Powdermet Inc/Terves Inc, US
The ability to design and manufacture highly engineered multiphase materials enables the independent (actually interdependent) control over physical and mechanical properties, and kinetic response of structural materials. The production of "materials that do more" offer [...]
